Single-point incremental forming (SPIF) is a technology that allows incremental manufacturing of complex parts from a flat sheet using simple tools; further, this technology is flexible and economical. Measuring the forming force using this technology helps in preventing failures, determining the optimal processes, and implementing on-line control. In this paper, an experimental study using SPIF is described. This study focuses on the influence of four different process parameters, namely, step size, tool diameter, sheet thickness, and feed rate, on the maximum forming force. For an efficient force predictive model based on an adaptive neuro-fuzzy inference system (ANFIS), an artificial neural network (ANN) and a regressions model were applied. The predicted forces exhibited relatively good agreement with the experimental results. The results indicate that the performance of the ANFIS model realizes the full potential of the ANN model.

Article Synopsis
- Optimizing enzyme thermostability is crucial for protein science and industry, but combining multiple mutations can lead to inactivation, making traditional methods slow and inefficient.
- Researchers developed an AI-driven method to enhance enzyme thermostability by efficiently recombining beneficial single-point mutations, using data from various mutant groups.
- After two design rounds, the study achieved 50 combinatorial mutants with 100% success, including one exceptional mutant that significantly increased melting temperature and half-life, while also revealing complex interactions (epistasis) among mutations.

This paper explores the development and application of the incremental forming process, an innovative method for manufacturing complex parts with high flexibility and low tooling costs. The review categorizes three key process variants: Single Point Incremental Forming (SPIF), Two Point Incremental Forming (TPIF), and Incremental Forming with Conjugated Active Plate (IFCAP). This study demonstrates the significant effects of these process variants on part accuracy and material behavior, particularly under varying process conditions.

Background: Magnesium (Mg) and its alloys are promising candidates for biodegradable materials in next-generation bone implants due to their favourable mechanical properties and biodegradability. However, their rapid degradation and corrosion, potentially leading to toxic byproducts, pose significant challenges for widespread use.
Objectives: This study aimed to address the challenges associated with Mg-based materials by thoroughly evaluating the biocompatibility, genotoxicity, and mechanical properties of Mg-based devices manufactured via Single Point Incremental Forming (SPIF).

Flexibility is crucial in forming processes as it allows the production of different product shapes without changing equipment or tooling. Single-point incremental forming (SPIF) provides this flexibility, but often results in excessive sheet metal thinning. To solve this problem, a pre-forming phase can be introduced to ensure a more uniform thickness distribution.

Single point incremental forming (SPIF) is becoming more and more widely used in the metal industry due to its high production flexibility and the possibility of obtaining larger material deformations than during conventional sheet metal forming processes. This paper presents the results of the numerical modeling of friction stir rotation-assisted SPIF of commercially pure 0.4 mm-thick titanium sheets.
